Today's proof that most people are bad at math

Of course, this would also bother me if it said $11.95 followed with "Less than a dollar a month."  Then, it wouldn't be a mathematical error, but an impracticality.

$11.95 / 12 is 0.99583 dollars per month, which translates to 99.58 cents a month.  If you buy this service, you're going to pay the whole year's service all at once.  However, let say they set up a monthly billing cycle and each month you had to pay them 99.58 cents.  It wouldn't matter what combination of legal coinage you could come up with to pay your bill, if you don't give them a full dollar, you'll have an unpaid balance.
